Important Safety Advice

Please read these instructions carefully before installing

or using this appliance. Failure to do so may result in

damage to persons and property.

Installation of this appliance must be carried out by a

suitably qualied competent person in accordance with

all Building Regulations, including those referring to Local

Authority Bye-Laws, National and European Standards

and Codes of Practice.

Do not install this appliance on a shared ue.

This appliance operates at very high temperatures and

retains its heat for a period after use. Do not touch any

surfaces while in use. All persons including children and

the inrm should be warned of this and not allowed to

touch any surfaces while in use. Please use a suitable

reguard to prevent contact when in use.

Do not place any photographs, paintings, TV’s or other

combustible items near the appliance as exposure to

hot surfaces will cause damage. Maintain safe distances

from combustibles in all cases in accordance with these

instructions – please refer to installation.

The operator must use the tools provided. The mitten

provided is a tool.

Do not t an extractor fan in the same room as this

appliance.

Ensure that there is adequate ventilation in the room in

accordance with building standards. Do not obstruct any

of the air inlets or outlets on the appliance.

A ue damper should not be tted when burning solid

fuels other than wood.

This appliance is for domestic heating use only in

accordance with these operating instructions. Do not

make any unauthorised changes to the appliance.

Only use recommended fuels. Do not burn petroleum coke

fuels, household waste or plastic in this appliance.

Burn only fuels with a low moisture content - burning soft

or wet fuels such as unseasoned timber or peat will only

result in a build up of tar in the stove and the chimney

and will cause staining of the glass.

Do not use ammable liquids to ignite the re.

Avoid the use of aerosols in the vicinity of the stove when

it is in operation.

Clean your chimney at least twice a year and clean the

ue way weekly to ensure there are no blockages. Do not

allow a build up of ash to occur in the ash pan as this will

cause the grate to burn out prematurely.

Regular maintenance should be carried out by a

Competent Engineer.

Assembly of the stove

To make the product easier for handling on installation, remove

the bafe plate, side bricks, back brick and door. Place these in

a secure place to avoid damage. These must be retted after

installation.

The legs and other xings are packed in the ashpan for safe

keeping in transport. Fix the legs to the underside of the product

using the bolts provided (Fig 2).

The stove is supplied ready for top ue connection. For Rear ue

connection remove the collar and blanking plates and t in the

desired position. The collar can be tted on the top or the rear of

the product. Seal with re cement to ensure it is air tight (Fig 3).

The primary air sealing plate is located on the front of the grate.

To locate in position, slacken the screws beneath the grate and

pull forward, then close the door fully, open again and tighten the

screws (Fig 4).

Installation Instructions

General

These instructions give a guide for the installation of the stove but

in no way absolves the installer from responsibilities to conform

to all relevant standards relating to the installation of solid fuel

appliances.

We recommend that for UK installations a HETAS registered

installer should be used, who will be able to give a Certicate of

Compliance that installation complies with Building Regulations.

In Ireland a registered installer from the Irish National Fireplace

Organisation should be used.

Please note that to the best of our abilities these instructions are

correct at time of printing, however we cannot be held responsible

for any differences in legislation which may occur in the future.

Chimney

Before installing, check the chimney is in good condition; dry and

free from cracks and obstructions. The diameter of the chimney

ue should not be less than 150mm and not more than 230mm.

If any of these requirements are not met, the chimney should be

lined by a suitable method by a qualied person.

The chimney height and the position of the chimney terminal should

conform to Building Regulations. If you have any doubts about the

suitability if your chimney, consult your local dealer or stockist. The

chimney must be swept before connection to the stove and swept

every six months thereafter.

Flue Draught

The chimney should be checked before the stove is installed to

ensure that there is adequate ue pull. The draught can be checked

initially by using a smoke match close to the ue opening. If the

chimney doesn’t pull the smoke it may suggest that the chimney

needs further attention.

The ue draught should also be checked under re at high output

and if it exceeds the recommended maximum a draught stabiliser

must be tted so that the rate of burning can be controlled and to

prevent over ring.

Wescott 5kW & 8kW

- 1 -

Any remedial work to the chimney ue should be carried out by a

suitably Qualied Engineer. A ue draught of minimum 12 Pascal

is required for satisfactory appliance performance.

An extractor fan must not be used in the same room as this

appliance.

Installation Clearances

The stove can be recessed in a suitable sized replace but a

permanent free air gap of at least 150mm must be left around the

sides and 300mm around the top to obtain maximum heat output

and for access to the rear of the stove (Fig 6).

Table 4 shows the minimum safe distances to combustable

materials that must be observed. Any surrounding combustible

material should not exceed 80°C.

Table 4 Sides Rear

Westcott 5kW 600mm 400mm

Westcott 8kW 600mm 480mm

Floor Protection

In all instances the stove should be positioned on a non-

combustible hearth. The construction of the hearth must conform

to Building Regulations, must be rm, non-combustible and capable

of supporting the stove.

Care should be taken to ensure the stove is level and the hearth

is secure. The hearth itself should not be less than 125mm thick,

including the thickness of the oor and any decorative top surface

(e.g. tiling). Allow an apron of at least 300mm at the front of the

stove in case of spills when de-ashing (Fig 6).

Place the product in the desired location on reproof hearth taking

note of installation clearances (Fig 7). Adjust the screws on the

bottom of the feet to ensure the stove is level and steady (see ‘A’

Fig 2). The stove can be screw xed to the oor when placed in

the desired position, using the holes provided in the feet.

Flue Pipes

The ue pipe used to connect to the stove should be made of

cast iron, 316 grade stainless steel or vitreous enamelled steel,

nominal thickness 1.2mm. The diameter of the ue pipe should

be 125mm (5”) for the Westcott 5kW and 150mm (6”) for both the

Westcott 8kW & 12kW models.

Connect the ue pipe to the stove making sure that it ts snugly

into the base of the ue collar (Fig 5). Seal the collar and ue

connection with re cement or with other suitable high temperature

sealant. Add ue sections as required; note that all ue sockets

must face upwards. Ensure that the ue pipe end is no closer

than 76mm to the side or rear of the chimney walls. It is essential

that all connections between the stove and the chimney ue are

sealed and made airtight.

Avoid using bends greater than 45° to the vertical (Fig 8). All ue

pipes should be as close to vertical where possible. For rear ue

connection the length of the horizontal run of the ue pipe should

not exceed 150mm (Fig 9).

Both chimney and ue pipe must be accessible for cleaning and

if ALL parts of the chimney cannot be reached, a soot door must

be tted to enable this to be done.

This product should not be installed on a shared ue.

- 2 -

Existing Fireplace

An existing replace opening can be bricked up or sealed with a

ue pipe may then be used to connect the stove to the chimney.

Ideally the old replace should be lled in so that there is a smooth

streamlined entry into the ueway. (Fig 9)

Typical installation for Inglenook Fireplaces

Inglenook replaces can have very large bore chimneys (Fig 10).

Check with your installer – you may need a stainless steel exible

ue liner for solid fuel tting.

Flue Damper (Not Supplied)

When burning wood, a ue damper may be tted to reduce the

draught through the stove if the draught is too high. When the

damper is set in the open position the chimney draws at full

draught, increasing the volume of air ow through the stove and

ue. Shutting the damper restricts the ow, slowing the rate of

burning.

The damper should be tted to the stove ue and should be the

same size as the ue pipe. As a rule it should be tted no closer

than 700mm from the ue outlet of the appliance.

A ue damper should not be tted when burning solid fuels

other than wood.

Flue Deposits

If the chimney was previously used as an open re, it is possible

that the higher ue gas temperatures generated by the stove may

loosen deposits that were adhering to the inner surface of the ue

pipe and may cause blockage of the ue pipe. We recommend that

in such a situation a second sweeping of the chimney should be

carried out within one month of initial stove use after installation.

Also lock or close off any existing dampers in the ueway.

Commissioning

Upon completion of installation, the stove and ue system should

be tested by a suitably qualied person to make sure it is safe for

normal use. A smoke draw test should be completed to check for

soundness of joints and seals and also that all smoke and fumes

are taken from the appliance up the chimney and emitted safely.

First warm the ue with a blowlamp or similar for about 10 minutes.

Place a lit smoke pellet on the centre of the grate with the air

controls open. Close the door – the smoke should be drawn up the

ue and be seen to exit from the ue terminal. Complete the test

with all windows and doors shut in the room where the appliance

is tted. If a ceiling fan is present it must be operated on max for

the duration of the test. If there are any extraction fans in adjacent

rooms these too must be operated on maximum setting during the

test with the interconnecting doors open. If any spillage occurs,

recheck the suitability of the ue system making sure there is

adequate air supply to the room (as per Building Regulations).

Light the appliance and slowly increase the temperature to

operating levels. Open the main re door when the appliance

reaches normal operating condition and carry out a spillage test

using a smoke match or pellet around the door opening. If any

spillage occurs, open all windows, allow the re to go out and

recheck the ue system and ventilation.

Operating Instructions

Warning: The door and operating handles become hot when

the stove is in use. For your safety use the glove provided.

Initial Firing of Stove

We recommend that you have two to three small res before you

operate your stove to maximum heat output. This is to allow the

paint to cure and the castings to relax and consolidate location.

We recommend this ‘running in’ procedure after long idle periods

to preserve the life of the stove. During this you may notice an

unpleasant smell. It is not toxic but for your own sake we would

suggest that during this period you leave all doors and windows

open.

Air Controls

Primary air is controlled via the sliding vents (A - Fig 11) in the

bottom of the door; this provides a conventional air draught to the

bed of the re. (+) indicates more air, (-) indicates less air, (+) and

(-) are marked on the primary and secondary air controls.

Secondary air is controlled via the sliding vent (B - Fig 11) above

the door. It is this ‘Airwash’ that keeps a clean and uninterrupted

view of the re, also aiding in good secondary combustion of fuel

and reducing emissions into the chimney and environment.

Lighting the Stove

Place re lighters or paper and kindling on the grate. Light the

re at base leaving all air controls open. Allow the fuel to reach

a steady glow and build the re up gradually. Once you have a

good re established across the grate bed, further fuel can be

added as required.

Running the Stove

When your fuel is well alight you can start to restrict the primary

air intake. If you are only burning wood the primary air control can

be fully closed. If you are burning solid fuel you will require more

primary air. Your stove is burning with maximum efciency when

a bright re is achieved using minimum air inlet.

The stove can be banked up for long periods. When burning solid

fuel empty the ash pan. Open air controls and let the re burn

brightly for a short period. Refuel and close air controls; the exact

setting required will depend on the fuel used and the chimney draw

so some practice may be necessary. To revive the re, open air

controls until the re is burning brightly, de-ash if necessary and

refuel. Set air controls as required. The stove is not suitable for

overnight burning.

Notes on Wood Burning

Wood burns best on a bed of ash and it is therefore only necessary

to remove surplus ash from the grate occasionally. Burn only

dry, well seasoned wood, which should have been cut, split and

stacked for 12 months with free air movement around all sides

of the stack to enable it to dry out. Burning wet or unseasoned

wood will create tar deposits in the stove and chimney and will not

produce a satisfactory heat output. When loading wood, make sure

that the end grain of the wood in the stove is pointing away from

the glass otherwise the moisture and gases coming from the end

grain of the wood will dirty the glass.

Notes on Solid Fuel burning (Other than Wood)

Always de-ash the grate before refuelling and do not let the ash

build up to the underside of the grate bars. Solid fuel produces

ash, which if allowed to build up will stie the air ow through the

grate and will eventually cause the re to die. It is important it is

to empty the ash pan after each ring of the stove. Air passing

through the rebed cools the grate. Distortion or burning out of the

grate bars is nearly always caused by ash being allowed to build

up on the underside of the grate. With some solid fuels a residue

of burnt fuel or clinker will accumulate on the grate. Allow the re

to go out periodically to remove this.

We recommend the majority of approved manufactured

smokeless fuels. Note that different types of fuel will give different

performances. Use as an incinerator for household waste is not

recommended as fumes from plastic, etc will cause pollution to

the atmosphere and will cause damage to the stove. Should any

difculties arise over fuel quality or suitability, consult your local

supplier or contact the Solid Fuel Advisory Service.

Petroleum coke fuels or household waste should not be

burned on this appliance.

De-Ashing

To de-ash the grate insert the notch on the riddle hand tool into

the peg on the side of the stove (D - Fig 11), then draw the tool

forwards and backwards with a slow positive action (Fig 12).

The ash pan should be emptied each time after operating the stove

so not to let build up of ash occur. Where possible, it is best to

wait until the stove and ash has cooled before removing the ash

pan. To remove, open the stove door by lifting the handle upward

(C - Fig 11) then using the riddle handle lift the ash pan out of the

re (Fig 13). For efcient burning of your appliance, make sure

the grate is clear of burnt debris; e.g. nails, etc.

Shut down Periods

If shutting down the stove for long periods (e.g. for summer months)

make sure that all ash is removed from the stove and that the

chimney ue ways and bafe plate are brushed clean. When the

stove is cold a vacuum cleaner may be used to remove any residual

ash or soot. Close the door and leave all air inlets open fully. This

action will ensure air circulation through the appliance and will help

to avoid corrosion and condensation within the appliance during

this shut down period.

Safety Notes for Your Guidance

FIRES CAN BE DANGEROUS.

Always use a re guard in the presence of children, the elderly

or the inrm. Inform all persons the dangers of high temperatures

during operation of the appliance including the stove pipe.

Use operating tools provided.

DO NOT OVER FIRE.

It is possible to re the stove beyond its design capacity. This could

damage the stove, so watch for signs of over ring. If any part of

the stove starts to glow red, the stove is in an over re situation

and the controls should be adjusted accordingly to reduce air

intake. Never leave the stove unattended for long periods without

adjusting the controls to a safe setting. Careful air supply control

should be exercised at all times.

Warning - Fume Emissions

Properly installed and operated, this appliance will not emit fumes.

Occasional fumes from de-ashing and refuelling may occur.

Persistent fume emission must not be tolerated. If fume emission

does persist, then the following immediate action must be taken:

1. Open doors and windows to ventilate the room.

2. Let the re out, or eject and safely dispose of fuel from the

appliance.

3. When the stove has cooled, check for chimney ue blockage

and clean if required.

Do not attempt to relight the re until the cause has been identied.

If necessary seek professional advice.

General Maintenance

Bafe Plate

This should be removed at least once a month to prevent any

build up of soot or ash, which could lead to blocked ue ways

and dangerous fume emission. If the bafe plate is removed the

chimney/ueway can be swept through the appliance.

Stove Body

The stove is nished with a heat resistant paint and this can be

cleaned with a soft brush. Do not clean while the stove is hot,

wait until it has cooled down. The nish can be renovated with a

suitable brand of paint.

Glass Panels

Clean the glass panels when cool with a proprietary glass cleaner.

Highly abrasive substances should be avoided as these can

scratch the glass and make subsequent cleaning more difcult. Wet

logs on heated glass, a badly aimed poker or heavy slamming of

the doors could crack the glass panels. The glass will not fracture

from heat.

Chimney

Check your chimney each year before starting to use your stove

for the winter. Birds may have nested in the chimney or masonry

may have cracked. Both chimney and ue pipe must be swept at

least once a year by a Qualied Chimney Sweep.

To avoid a build up of soot on the bafe plate (the plate inside the

stove above the grate) it must be removed and cleaned periodically.

This plate locates the back and side rebricks so note its position

before removal. To remove, lift plate and remove one side brick;

this will allow the plate to drop and aid removal. To replace, position

bafe plate on back and side plate, lift plate and replace remaining

brick, making sure it has located in position. This must be done

when the stove is cold.

Troubleshooting

1. Poor heat output

a. Stove too small for room: Seek advice from a Qualied Heating

Engineer as to (kW) output required for the room size. As a

guideline the volume of the room in cubic feet divided by 500;

e.g. room 15’x15’x8’ would require 3.6kW approx.

b. Chimney and/or ue pipe restricted, room ventilation restricted:

On installation these should have been checked but regular

maintenance is necessary as conditions can change; e.g. soot

build up, birds nesting, masonry fall, dust build up or furniture

blocking vents.

c. Poor quality fuel: Only burn dry seasoned timber, soft woods

have a lower heat output than hard woods per hour. Solid

fuels vary in heat value; check with your coal merchant as to

suitability.

2. Dirty Glass Panel

a. Generally caused by poor fuel quality, see (1c)

b. Use secondary air slide (Airwash) for glass panel

c. Fire burning too low, open air vents on stove to create hot re;

this may ‘burn’ glass clean.

d. If glass requires cleaning use glass cleaner recommended by

your supplier; only use glass cleaner on cold glass. DO NOT

USE any abrasives or scrapers as these will scratch glass and

increase future tar build up making it harder to clean.

3. Unburnt Fuel in Firebox

Insufcient air reaching fuel. Open primary air slide, this will supply

combustion air to burn fuel fully (unless it has reached a ‘point of

return’)

Check if the ash pan is full and empty if required. De-ash with the

riddler to make sure the grate is not blocked and check for jammed

clinker or nails when the re is out and the stove has cooled.

4. Smoke and Fumes Entering Room

These are very dangerous and must NOT be tolerated. Open

window and allow re to burn out. Seek expert advice immediately.

DO NOT USE stove until the problem is solved.

5. Chimney Fire

Identied by loud roaring sounds, dense smoke and sparks emitting

from chimney. Shut down the air supply by closing air vents,

close stove door fully and call re brigade immediately. Regular

chimney maintenance will prevent chimney res. Seek advice from

a Qualied Chimney Sweep. Chimneys must be checked annually

and more often when bitumas coal and poor quality smokey fuels

are used.
